Abstract

An electrode for a metal-ion battery is provided wherein the active layer of the electrode comprises a plurality of low porosity particles comprising an electroactive material selected from silicon, silicon oxide germanium, tin, aluminium and mixtures thereof and a plurality of carbon particles selected from one or more of graphite, soft carbon and hard carbon. The ratio of the D50 particles size of the carbon particles to the D50 particle diameter of the porous particles is in the range of from 1.5 to 30. Also provided are rechargeable metal-ion batteries comprising said electrode and compositions of porous particles and carbon particles which may be used to prepare the active layer of said electrode.
